HYMENOPTERA. 189 



of Andrena. The mouth-parts do not appear to be essentially differ- 

 ent from those of the Andrenids, and many characters of the abdo- 

 men, wings, etc., are strongly suggestive of Andrena. These re- 

 marks are based on the European M. labiata; the American M. 

 ciliata has an abdomen strongly recalling Exomalopsis solani. The 

 American M. steironematis Rob., with its densely punctured abdo- 

 men, looks very different from labiata or ciliata, but it has the 

 Macropis mouth. 



AMTHOCOPA Lepeletier and €HAL,ICODOI»I A Lepeletier. 

 Mr. Vachal observes that Lepeletier cared more for the habits 

 than the form of bees, for founding generic groups; thus Anthocopa 

 (wrongly credited by Ashmead to Latreille) was based on Osmia 

 papaveris Latr., which is a petal -cutting bee, thus resembling the 

 leaf-cutting megachile; while Chalicodoma, a Megachiline, makes 

 mud-mortar cells. 



IIOKKMIMA Dalla Torre. 



As Mr. Vachal says, this was merely a new name for Epeicharis 

 Rad., and so cannot differ from it. Ashmead has a separate genus 

 called Florentina, D. T., apparently intending Fiorentinia. The 

 characters given by Ashmead for " Florentina " appear to belong to 

 Fiorentinia; those given by him for Epeicharis Rad. do not belong 

 to that genns, the maxillary palpi being said to be two jointed. Is 

 there not some confusion with Epicharis Klug. ? 



EPK'LOPUS Spinola. 

 This genus ("Epicolpus" in Ashmead) is said by Mr. Vachal not 

 to be an Anthophorid, but to be hardly separable from Melecta. Its 

 blue color is peculiar. In this connection one may remark on the 

 beautiful and extraordinary patches of bright blue appressed pubes- 

 cence on the head, thorax, legs and especially abdomen in Crocisa 

 splendidula Lep. from Africa, a specimen of which I owe to the 

 kindness of Mr. Vachal. Something of the same sort is seen in 

 Ash mead's Xylocopid genus Cyanosderes.
